Any reason to think it's NOT the Throttle Position Sensor?
I've researched all the threads, my 2007, DL650A has all the classic symptoms:
Warm engine, pull in the clutch, let go of the throttle the tach lands anywhere from 1,400 to 0. It's pretty random. If it's low, you goose the throttle and it lands back at 1,400 until next time.
I did the three full throttle pulls with the key "on" and fuel pump primed, engine not yet satarted and it had no effect good or bad. I've never done this before and noticed an od electrical asound like "nano' with evey throttle pull.
Here's the odd thing: This only started after I installed Oxford heated grips. I didn't touch anything under the airbox, but cleaned and re-installed the air filter. The grips were connected at the battery and they work fine. Disconnected the grips and the problem persists. The grips came with a cheesy multi-pin connector which had a bent pin. After several attemts to straighten it out with tweezers I got it to work. This required several sequences of disconnecting and re-coonecting the battery leads.
I did have this idling problem briefly and to a lesser degree in March. It disappeared after I got the bike back from the dealer who did a major servicing: Throttle Body Synch, Valve Check, Coolant Replacemant, Oil Change, Air Filter Replacement.
I've since put 10,000 miles on the bike with no problems at all until after the grips install.
Is there something I could have inadvertently done in routing the grip wires, under the tank, or is it just coincidence?
Oh, to make it more frustrating my local dealer just told me that the Throttle Position Sensor is on backorder from Suzuki.
